[0040] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] Example 1: As shown in the attached Figure 1 To the attached Figure 6 As shown:

[0042] The utility model provides a motor end cover rapid drilling device, comprising a fixed frame 1, a movable component 2 and an assembly structure 3;

[0043] A movable T-slot 101 is provided on the inner side of the top of the fixed frame 1, and a screw rod 1011 is rotatably installed inside the movable T-slot 101. One end of the screw rod 1011 is fixedly connected to the first motor 102. A movable T-block 201 is provided inside the movable T-slot 101. The bottom of the movable T-block 201 is fixedly connected to a connecting slide frame 202. A sliding support frame 204 is provided on the outer side of the connecting slide frame 202. A second motor 205 is fixedly installed on the sliding support frame 204. A driving end of the second motor 205 is fixedly connected to a mounting collar 301. Sliding support holes 3011 are provided on both sides of the mounting collar 301. An extrusion groove 3023 is provided on the outer side of the sliding support hole 3011. Guide grooves 3012 are provided at the upper and lower ends of the extrusion groove 3023. The sliding support hole 3011 is provided with a guide groove 3012. The cam 3031 is provided on one end of the sliding support 302, and the cam 3032 is provided on the left and right sides of the sliding support 302. The sliding support 302 is fixedly connected to the outer side of the sliding support 302 with a fixing ring 3021. The two sides of the fixing ring 3021 are fixedly connected with locking blocks 3022. A spring 3024 is provided inside the extrusion groove 3023. One end of the sliding support 302 is fixedly connected to the handle 3025. The interior of the mounting collar 301 has an assembly groove 303. The assembly groove 303 is installed with an assembly plug 3031. The assembly plug 3031 has a locking socket 3032. The other end of the sliding support 302 is inserted into the locking socket 3032. The bottom of the assembly plug 3031 is fixed. A drill bit 3033 is connected, a first screw hole 2011 is provided on the mobile T block 201, and slide grooves 2021 are provided on both sides of the connecting slide frame 202. A cylinder 203 is fixedly installed on the connecting slide frame 202, and a slider 2041 is fixedly connected to the inner top of the sliding support frame 204. The slider 2041 is slidably installed in the slide groove 2021, and a push support plate 2042 is fixedly connected to the middle of the sliding support frame 204. The driving end of the cylinder 203 is connected to the top of the push support plate 2042. By starting the first motor 102 to drive the screw rod 1011 to rotate, the screw rod 1011 is rotatably engaged with the first screw hole 2011 on the mobile T block 201, but the mobile T block 201 is limited in the mobile T groove 101, so that the screw rod 1011 drives the mobile T block When the screwdriver bit 3033 is unlocked, the user can manually unlock the screwdriver bit 3033 by manually unlocking the screwdriver bit 3033. When the user unlocks the screwdriver bit 3033, the user can manually unlock the screwdriver bit 3033 by manually unlocking the screwdriver bit 3033. When the user unlocks the screwdriver bit 3033, the user can manually unlock the screwdriver bit 3033 by manually unlocking the screwdriver bit 3033.This pushes the fixed collar 3021 to move, which drives the sliding pillar 302 to return to its original position and insert it into the locking hole 3032. Then, the handle 3025 is rotated to rotate the locking block 3022 to the horizontal position, so that the locking block 3022 is locked into the locking slot 3014, thus completing the installation and preventing the spring 3024 from being unable to restrain it due to centrifugal force during rotation.

[0044] Example 2: Based on Example 1, Figure 6 As shown, the inner bottom end of the fixed frame 1 is provided with a positioning structure 4, which includes a bearing support plate 401, a bidirectional screw rod 4011, a guide rod 4012 and a worm gear 4013. The inner bottom end of the fixed frame 1 is fixedly connected to the bearing support plate 401, and a bidirectional screw rod 4011 is provided on one side of the top of the bearing support plate 401. A guide rod 4012 is provided on the symmetrical side of the bidirectional screw rod 4011. One end of the bidirectional screw rod 4011 passes through the fixed frame 1 and is fixedly connected to the worm gear 4013 on the outside. The worm gear 4013 is rotatably engaged with the worm 4021 at the bottom. The worm 4021 is rotatably installed in the interior of the rotating bracket 4022. At the same time, one end of the worm 4021 is fixedly connected to the third motor 402. The top of the bearing support plate 401 is provided with two sets of positioning members. The positioning clamp 403 has connecting protruding plates 4031 fixedly connected on both sides of the positioning clamp 403, and the connecting protruding plates 4031 are respectively provided with guide holes 4032 and second screw holes 4033. By starting the third motor 402 to drive the worm 4021 to rotate, the worm 4021 engages with the worm wheel 4013 to rotate, and the worm wheel 4013 drives the bidirectional screw 4011 to rotate, so that the bidirectional screw 4011 rotates and engages with the second screw hole 4033 on the connecting protruding plate 4031 on one side of the positioning clamp 403, but the connecting protruding plate 4031 on the other side of the positioning clamp 403 is guided by the guide hole 4032 on the guide rod 4012, so that the bidirectional screw 4011 drives the two groups of positioning clamps 403 to move toward each other, thereby clamping and positioning the motor end cover.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In the present invention, the motor end cover is first placed on the bearing support plate 401, and then the third motor 402 is started to drive the worm 4021 to rotate, the worm 4021 engages the worm wheel 4013 to rotate, and the worm wheel 4013 drives the bidirectional screw 4011 to rotate, so that the bidirectional screw 4011 is rotated and engaged with the second screw hole 4033 on the convex plate 4031 connected to one side of the positioning clamp 403, but the convex plate 4031 connected to the other side of the positioning clamp 403 is guided by the upper limit of the guide rod 4012 through the guide hole 4032, so that the bidirectional screw 4011 drives the two sets of positioning clamps 403 to move toward each other, thereby clamping and positioning the motor end cover, abandoning the manual adjustment of the clamp and adopting an electric method to be more efficient. It is portable, ensures stability during drilling, avoids offset, and facilitates the rapid adjustment of the drill bit 3033 to the drilling position, and then starts the first motor 102 to drive the screw rod 1011 to rotate, and the screw rod 1011 rotates and engages with the first screw hole 2011 on the movable T block 201, but the movable T block 201 is limited in the movable T slot 101, so that the screw rod 1011 drives the movable T block 201 to move, thereby adjusting the drill bit 3033 to the drilling position, and then starts the second motor 205 to drive the drill bit 3033 to rotate, and then starts the cylinder 203 to push the sliding support frame 204 to move on the outside of the connecting slide frame 202, so that the drill bit 3033 moves downward, thereby drilling the motor end cover.
